Chapter 1816

Hearing this, Chumo didn't know what to say, so he had to smile back: "you say, I'm listening."

"How did you get down just now? Also, how do you control the left and right in the air? Has the direction been affected?"

Zhang Feng asked seriously. Now he is not in the mood to joke with this guy, because it involves the transformation of hot-air balloons, and hot-air balloons involve people, so he can't be careless.

Seeing that Fengzi was so serious, Chumo also put away his smile and began to recall his feelings in the sky just now.

They also probably saw the importance of the matter. They didn't bother and didn't dare to speak. They just roasted the fire silently to vent their emptiness.

After a short time, Chumo smiled again and exclaimed, "I thought of it."

As soon as the voice fell, another dry wood stick flew over: "you're going to die, keep your voice down."

"Oh, oh."

Chumo nodded foolishly, then looked at Zhang Feng and said with a smile: "Fengzi, I just thought that when I was in the air, the direction was completely affected by the wind. I had no way at all. It was relatively simple when I came down. The fuel was almost burned out. Then I fell down slowly and fell a fart. The thigh pier still hurts."

With that, he touched his fart and looked pitiful: "if you don't believe it, I'll show you."

"Get out."

Zhang Feng frowned, stared at Chumo, and then fell into deep thought.

If, as iron bull says, people can't control the direction in the air and are completely taken away by the wind, you know, this guy has more than 200 kilograms. Such a heavy silly goods can't be controlled in the sky, not to mention others. Although he has some ropes tied to him, it's also for the sake of safety.

It seems that we must install something on the hot-air balloon that can control the direction, otherwise, this hot-air balloon will be very dangerous in the future.

Just as he was thinking about how to solve it, a cry woke him up.

"Hiss... Ah..."

Hao Chujun held his hands and screamed in situ. It seemed that he felt a little uncomfortable.

"What's the matter with you?"

Zhang Feng came forward and asked.

"Teacher, I just picked this coal. I thought there was a stabbing pain. That's it."

Hao Chujun showed his right hand to Zhang Feng. He was helpless.

Zhang Feng looked at Hao Chujun's right hand. There was no trauma on the surface, no stabbing, and no trace. What's going on? He glanced at the burned coal, picked up a stick and stretched out to the coal.

"Teacher, wait a minute."

Hao Chujun suddenly got up, looked at Zhang Feng and said, "master, it hurts. Please don't try. If master insists, let the disciples come."

Zhang Feng waved and refused, "it doesn't matter. I want to know what this is?"

With that, without waiting for a reply, he directly took the stick and stretched it out to the coal. At this moment, a stabbing pain came, as if he had been electrocuted.

No, this is electricity.

But the voltage is very low, just like static electricity.

Is there voltage on this coal?

He was a little unbelievable, but he decided to try again.

The stick extends to the coal again. It still feels like voltage, that is, voltage.

His eyes are prominent and his cheeks are red. He doesn't know how to describe the mood at the moment and cheer it out?

It is estimated that the guy in front of him didn't even know what the electricity was. He had to caress his chest, touch a cigarette with his trembling right hand, hold it in his mouth, light it slowly, and look at the coal excitedly.

At the moment, he remembered the doomsday battery of later generations, which was made of low voltage on coal.

Now that you have found this thing, can you also make a doomsday battery?

With the doomsday battery, isn't hydrogen readily available?

At the thought of this, he was excited, and his smoking hands were shaking.

On one side, Hao Chujun saw the abnormality and hurriedly came forward and asked, "mentor, what's the matter with you?"

"Electricity, this is electricity."

Zhang Feng could no longer suppress his joy and exclaimed.

But the people around them looked confused. They didn't know what electricity was. They asked curiously, "what is electricity?"

"Electricity, electricity is..."

Zhang Feng kept stamping his feet and didn't know how to explain it to everyone.

Is electricity a natural phenomenon? Naturally?

Isn't this more and more confusing?

"What is electricity?"

Chumo is a little impatient and feels ashamed to ask questions.

But Zhang Feng was disgusted with this shameless question at the moment, because he couldn't explain what electricity was, so he had to start fooling everyone: "have you seen lightning before?"

The crowd nodded.

Zhang Feng clapped his legs and exclaimed, "lightning is electricity, but it's a little different from the electricity just now."

"What's the difference?"

Ma Zhou tilted his neck and asked.

"You..."

Zhang Feng had planned to yell at him, but when he thought that he was his own student, he endured it and recited in his heart. He was a fool. Don't worry. Then he put a generous smile on his face and stroked Ma Zhou's head: "good boy, this is not something you can involve now. You'd better read the Three Character Classic."
